This was supposed to be the calm after the storm. We've just finished a wild year on the local political scene: Scott Brown and Elizabeth Warren faced off in the nation's marquee US Senate race; a down-and-dirty North Shore congressional battle pitted John Tierney against Richard Tisei; Joe Kennedy III gave us the first campaign of the famous family's next generation; and of course former governor Mitt Romney ran his down-to-the-wire presidential quest out of North End headquarters.

With the dust settled, Boston's political insiders were looking forward to a quiet 2013 — a municipal election year, with Boston's Tom Menino expected to cruise to re-election. But, barely a week after the November 6 election, the Massachusetts political world was right back in the maelstrom.

Two deepening mysteries were responsible.

First, the Washington Post reported early last week that President Barack Obama is considering US Senator John Kerry for his second-term secretary of defense.

This unleashed a torrent of near-hysterical telephone and text activity about potential candidates for a special election. Kerry was known to be eager to succeed Hillary Clinton as secretary of state, but reporting and rumor suggested that he would get passed over again, this time for Ambassador to the United Nations Susan Rice. The Post article re-opened the possibility.

At around the same time as that Post bombshell, the Boston Globe dropped another: Mayor Tom Menino, already in the hospital for two weeks dealing with a viral infection and blood clot, had "suffered another setback" with back pain and would remain at Brigham & Women's indefinitely.

All of a sudden, political insiders were gossiping about who was planning to run if the 69-year-old Menino can't. A press conference on his behalf fanned the flames. "Insiders are going crazy over his health [and] re-election prospects," one campaign operative told me.

Of course, neither race might actually materialize. But it feels like the campaign cycle never ended — oh, and Lieutenant Governor Tim Murray essentially kicked off the 2014 gubernatorial campaign last Thursday, with a Greater Boston Chamber of Commerce speech that all but declared himself a candidate. It seems like everybody in town is gearing up to run for something.

USUAL AND UNUSUAL SUSPECTS

Brown has signaled that we can expect him to return as the GOP standard-bearer if Kerry does leave — even though, should Brown win, he'd need to defend the seat in 2014 (when Kerry is next due for re-election), putting him through four tough statewide campaigns in less than five years.

The indefatigable Brown is one of the few people who would be undaunted by that prospect. One of his top aides, Jerry McDermott, posted on Facebook shortly after the Post article appeared: "Team Scott Brown. Hope you had some much needed rest. Looks to be a busy 2013 and 2014."

Democrats are mostly talking about the usual suspects — members of Congress, former congressman Marty Meehan, those who have run before — because the shortened timeframe of a special election probably makes it too hard for anyone else to raise money and gain traction against Brown.

But if they were all to take a pass, there could be an opening for lesser-knowns to vie for the chance. State Senator Ben Downing of Pittsfield, Fall River mayor Will Flanagan, former New Bedford mayor Scott Lang, Suffolk County sheriff Andrea Cabral, and businessman David D'Allesandro are names being tossed around.

A Statesman Too Late? The congressional debt "super committee" has begun its work, and already there are signs that its task is hopeless.

Seeing things Early last week, US Senator Scott Brown claimed to have seen pictures of the dead Osama bin Laden, which he implied were shown to him in briefings. Hours later, his office put out word that the photos Brown had seen were not "authentic."

The Kennedys will rise again! As you've probably heard a couple thousand times by now, Rhode Island Representative Patrick J. Kennedy's retirement means Washington is without a member of Team Camelot for the first time in 64 years.

Coakley for Senate When Massachusetts voters go to the polls on Tuesday to elect a successor to the late Senator Edward Kennedy, they face a choice that is as clear as the difference between black and white.

Burn Baby Burn Last Thursday afternoon, moments after I posted on Facebook about the death of the climate-change bill, I got a message from a surprised and disappointed Laura Everett.

Great Scott After months without new polling on the high-profile Massachusetts Senate race, four firms took the pulse of the race in February — all finding incumbent Republican Scott Brown ahead of presumed Democratic nominee Elizabeth Warren.

Thrill and Agony The vote totals that poured in through the state secretary's office November 6 provided one set of winners (Elizabeth Warren, John Tierney, Joe Kennedy III, medical marijuana) and losers (Scott Brown, Richard Tisei, medical suicide). But there were plenty of other victories and defeats in Bay State politics last Tuesday.

The Phoenix endorses... A strong voice of reason on many issues, former Cumberland County sheriff Mark Dion is a solid supporter of medical-marijuana access, providing a powerful law-enforcement perspective that is credible because of his experience and his depth of thought about the larger issues at hand.

The Obama imperative Two things stand between almost certain economic and social catastrophe: the prospect of the Democrats maintaining — or expanding — their majority in the Senate, and the reelection of President Barack Obama.

Just Say No The key to understanding American politics these days is recognizing that it's easier to oppose a candidate or policy than it is to promote one of your own.
